Take a plane to the Ming Dynasty

Chapter 237 Foundation pouring
Everyone else is laughing.

Including Yan Hong and Zhu Changning, they were all amused by this young resident.

However, Zhu Changyuan didn't smile, instead of smiling, he frowned deeply, showing extraordinary worry: Yes, if it wasn't for this resident's reminder, I almost forgot about the imbalance between men and women, but the island is the most developed obstacles.

Either buy or loot, but no matter what method is implemented, it must be resolved imminently.In any case, neither a mature town nor a city can do without women.

"Huh!" Zhu Changyuan looked at the resident, and suddenly remembered the girl who had promised the soldiers brothers to go to Fusang country to snatch devils when he led the army in Dalinghe, sighed, and said: "You step back, Ben I will bring back a daughter-in-law to each of you next year."

"Thank you, General."

After sending away the soldiers, Zhu Changyuan frowned slightly, and said to the merchants beside him, "Well, from today onwards, the meat, vegetables, fruits, clothes, and even grain on the island will all be entrusted to you to transport them from the land. Sales, after your items arrive, this general will remove his items from the shelves to benefit merchants. What do you think?"

"Oh, that's really, thank you, General." These were originally lucrative businesses, but Zhu Changyuan didn't expect Zhu Changyuan to give in, and the merchants were moved from the bottom of their hearts.

Zhu Changyuan can also benefit.

In this way, not only can the merchants get enough benefits, but also solve another headache for Zhu Changyuan: less land and more people.

As long as these merchants are tied to the boats, they will continuously deliver food from all over the world, and the biggest obstacle restricting population development on Riyue Island will no longer exist.

As for the output of the land on Riyue Island, it can be stored for future use. Once the line of merchants is cut off, at least self-sufficiency can be guaranteed; when the population of the island increases in the future, even if it cannot meet the needs, there will still be Gu Changzuo Songhu The back road of 180 million mu of land in the area.

In the future, you will be able to save yourself the hard work and tediousness of transporting food from modern society.

After the policy was formulated, Zhu Changyuan didn't have to worry too much about Yan Hong and Zhu Changning's implementation. In the next few days, he traveled back to modern society and transported a large amount of tools for pouring concrete, especially shovels. Nearly [-] shovels were purchased, almost buying all the shovels in Nandu City.

The shovel is used in many places, not just for pouring concrete.

Three days later, the weather was fine.

Although it was still cold, Yan Hong organized all the workers to clean the road up the mountain early in the morning, and at the same time cleaned the entire mountain top without any snow.

The foundation pit was dug, and the two 15-meter-square and [-]-meter-deep foundation pits were about [-] meters apart.

Next to the foundation pit, there are hill-like stones and sand piled up, as well as neatly stacked steel bars that have been processed; a 130-ton and a [-]-ton crane are placed not far away .

There are two large oil tanks next to it. Gasoline and diesel are full of iron drums. Next to it is a large simple warehouse built of bricks and stones. Inside are rows of bags of cement, covered with tarpaulins. Cover it with plastic paper, although the wind and snow are very strong, it will not damage the quality of the cement.

Regardless of the coldness, Zhu Changyuan ran up the mountain, smiled in the face of the strong wind, and said, "The wind here is really strong. It seems that the location of the generator set here is really good."

There are more than a thousand people in the dark area on the top of the mountain, all of them are ready to go and prepare for the next job.

"Start work!" A technician in a black padded jacket gave an order, and more than 20 technical masters, each leading [-] or [-] workers, began to resist, install, and weld steel bars.

Then there are technicians holding instruments to observe and locate from time to time!
Zhu Changyuan went down the mountain after looking at it, and said to Yan Hong: "With so many people, the steel bars of a foundation pit plus those pre-embedded rings and pre-embedded parts can be installed in one day. The next most important thing is What do you think about getting someone to pour the concrete,"

Yan Hong said: "The subordinate plans to organize 2000 people to mix at the same time. Even if one person can only mix one side a day, the task can be completed."

Zhu Changyuan asked with a smile: "The terrain is so high on the mountain, can the water for mixing concrete be prepared? The weather is so cold, how to ensure the quality of the entire project?"

"This!" Yan Hong thought about it carefully, and said: "I will make arrangements immediately, and arrange for someone to fetch water from the river below, and then transport it to the top of the mountain in a horse-drawn carriage."

"Well, there is one more important point." Zhu Changyuan thought about the general procedure, and said: "The weather should be sunny tomorrow, so you can find someone to send more firewood to the mountain today, and the water for mixing concrete will be heated to [-]% tomorrow." Hot, all vibrators and machinery are guaranteed to work."

"If it's a night shift, you also need to consider the night lighting, the food for the workers at night, etc., and you must carefully consider the arrangements and make practical arrangements."

"Yes, General."

Yan Hong went down to make some arrangements and got everything ready.

Sure enough, as Zhu Changyuan predicted, the steel bars were bound and the pre-buried things were installed in one day.

Next, it will be a hard battle.

Zhu Changyuan was worried, so he ran to the top of the mountain and even taught the workers how to do it.

In fact, the workers were already proficient without his demonstration, because half of these workers followed Lao Jiang in construction, and poured concrete for countless times.

But this time is different, Zhu Changyuan attaches great importance to it.

A 15-meter-long, 15-meter-wide, and 1000-meter-deep foundation pit requires more than [-] square meters of concrete even if it is excavated in a compact manner. In addition, it is difficult to excavate these rocks, and it is necessary to over-excavate a lot. Naturally, the amount of concrete used is up.

The advantage of this construction is that there is no need to make formwork, but the disadvantage is that concrete is wasted.

The foundation pit is only 60 meters in circumference when it is fully built for one week. Zhu Changyuan asked all the people to back off for a certain distance, and two people worked in groups, and then began to manually mix the concrete on site. The foundation pit can only accommodate about 200 people. There are a total of [-] teams, and one team has to manually mix [-] cubic meters of concrete.

The weight of one square of concrete is two and a half tons, and the weight of fifteen squares is about [-] tons less. The workload is still quite large.

"Let's start." Zhu Changyuan ordered, and the workers started immediately.

Firstly, workers who specialize in transporting materials deliver sand, gravel and cement to the site and hand them over to those who are responsible for mixing around the foundation pit.
The mixing workers mixed the sand, gravel and cement evenly according to the ratio Zhu Changyuan said, and then someone who specialized in boiling water brought buckets of boiling water with large plastic buckets.

Pour boiling water on it and mix it with the cold sand and stones, and the temperature suddenly drops. Fortunately, although the temperature has dropped a lot, it is finally not below zero.

After pouring water on the sand and gravel cement, a group of two people started to shovel and turn quickly. It took about 3 minutes to mix everything evenly and turn it into a good-colored concrete.

A bag of cement is mixed once, and it looks like a big pile, but it is only [-] cubic meters. Just this [-] cubic meters of concrete weighs a full [-] kilograms, or [-] catties.

When the concrete is mixed, it is then scooped up one by one and thrown into the foundation pit.

After all the mixed concrete is thrown away, the material transporter will transport the second sand and gravel material, which can be regarded as a cycle.

Zhu Changyuan made a rough calculation. It takes an average of ten to 15 minutes to operate one cycle. If the two workers cooperate well in one hour, they should be able to mix one and a half.

But this is impossible, because when Zhu Changyuan counted, the workers had just started working and were not yet tired. If they were tired, it would be good to mix one side for an hour.

Adding up the people around, an hour is fifty square meters.

Five hundred cubic meters in ten hours, and the total cubic volume of this large foundation pit can reach about 27 cubic meters (including over-excavation). Excluding the time for workers to eat, it will take [-] to [-] hours even if they do not rest.

It is cold in winter, and the efficiency of work will be compromised if you work overtime at night, so basically don't expect to finish the work in less than [-] hours.

The weather was very cold, but Zhu Changyuan didn't leave. Although he didn't work, he stayed with the workers on the mountain all the time, not to encourage the workers, let alone to supervise them.

That's because this basic project is of great significance to him, and it is an invisible lifeblood for the entire Sun Moon Island, and it must be done well to be sure.

Now even if he is sent to the room and tucked into the bed, he still cannot sleep.

One hour, two hours.

Two hours later, the concrete in the foundation pit had begun to show its scale.

"Buzzing." The pumper started the concrete vibrating pump and began to vibrate the poured concrete to prevent quality defects.

Generally, it takes two hours for concrete to reach the initial setting, but in winter the weather is cold, and the setting speed will be much slower, so it is still effective when it is vibrated in the second hour.

As the sun rose higher and higher, the concrete in the foundation pit also became higher and higher. The vibrator kept vibrating, and the mixing personnel threw in the hot concrete that had just come out of the oven from time to time.

At noon, the food was delivered, and the workers took turns to eat, and they were not allowed to rest after eating, and had to continue to work.

Zhu Changyuan ate and lived with the workers at the construction site. Of course, although it was a construction site, the food was not bad. Not only rice and meat, but also two hard-boiled eggs were distributed to each worker to satisfy their hunger when they were hungry for a long time.

Another afternoon passed, and the concrete in the foundation pit was less than half.

Before night fell, the electrician pulled out a special wire from the generator, and tied more than ten kilowatt light bulbs around the foundation pit at one go, illuminating the site as if it were daytime.

The workers were sleepy and torn, but Zhu Changyuan didn't allow them to stop, not because he was cruel, but because the project really couldn't be delayed.

At eight hours on No.20, the foundation pit was finally completed, but the completion of the foundation pit does not mean that all these things are over.

Zhu Changyuan asked the workers to go back to rest, and Lao Jiang transferred a group of people to bring thick geotextiles from the warehouse. When the concrete on the upper floor was hard enough to stand on, he quickly spread the geotextiles on it to keep the concrete warm. .
